Romantic comedy about destiny and the possibilities of a chance encounter evolving into a close encounter of the happily-ever-after kind. Oliver (Ashton Kutcher) and Emily (Amanda Peet) set off sparks as opposites who attract and have a one-flight stand from LA to New York. When the trip's over, they are too - and both move on but can't really let go. As they search for love that doesn't end in disaster, they keep finding each other. And while the chemistry that first brought them together keeps generating heat, the timing is always wrong.
